MOLLUSC A OF OHIO. '.\T 



Polygyra hirsuta (Say, Helix.). 



Over the state, common. Albinos are not infrequent. 

 Polygyra fraterna (Say, Helix). 



• • Over the state, common, albinos are occasionally found. 



• • This is what has been taken for monodon Rackett, plus 



• • var. fraterna in earlier descriptions and lists. 

 Polygyra monodon (Rackett, Helix;, leai Ward. 



Cincinnati; Columbus; lake islands! (Allen); Defiance (St.). 

 Not found e. g. in Tuscarawas Co. This is the Helix 

 leai, or monodon var. leai of descriptive works and lists. 

 At least in Ohio, the two species appear to be distinct, 

 and have always been so regarded by the Cincinnati 

 and Columbus conchologists ; at Defiance, I have found 

 the two side by side, without any intermediate spec- 

 imens. 



PHILOMYCID^E. 



Philomycus caroliniensis (Bosc, Limax), Tebennophorus caro- 

 liuieusis G. W. Binney. 

 Over the state, common, but becoming rare in many sec- 

 tions. Variable, and its color variations are said to 

 indicate varieties and even distinct species, by some 

 conchologists. These slugs should be carefully collected 

 and studied. 

 fPhilomycus sp. — pennsylvanicus Pilsbry? X 



Near Chippewa Lake (St.). Decidedly distinct from the two 

 other species. About 30 mill, long, slender, light col- 

 ored, the sole tinged with blood-red; the jaw has a 

 number of somewhat rib-like, irregular ridges. The 

 animal is as active as a Limax. 

 fPhilomycus dorsalis Binney, Pallifera dorsalis Morse. X 



Tuscarawas and Defiance Counties (St.); probably over the 

 state, but overlooked. (It is in none of the Cincinnati 

 catalogues.) 



EXDODOXTID.€. 



Patula [Pyramidula] solitaria (Say, Helix). 



Over the state, less common than the following. 

 Patula alternata (Say, Helix). 



Over the state, common, at some places abundant. Albinos 

 are found occasionally, also reversed (sinistrorse) 

 specimens, e. g. at New Philadelphia (St.). 

 Patula perspectiva (Say, Helix.) 



Over the state, common, preferably in the forests, on and 

 in decaying wood. Albinos are found occasionally. 

 Patula striatella (Anthony, Helix). 



Over the state, common, preferably in the open.
